General Sargas Ruk is the Grineer boss of Saturn. As one of the highest-ranking figures in the Grineer military, he plays a role in a number of Operations. His Assassination mission can be found on a Grineer Galleon at Tethys, Saturn.
Lotus: "General Sargas Ruk has become a problem for our artefact recovery efforts. Several of our dig sites in this sector have been attacked and annexed by Ruk and his fleet. Take Ruk out."
Lotus: "Ruk is the Grineer's preeminent artefact hunter. Taking him out will cripple their artefact recovery efforts."
Lotus: "Ruk sees flesh as a flaw. As a result, he has built a profitable artefact smuggling outfit to finance his search for the best in Grineer body modifications and augmentations.
Lotus: "Ruk will be adorning only the most impressive in Grineer body modifications. You will need to stay one step ahead of him."
Lotus: "Ruk is nearby. Be warned that he is a formidable adversary, with an almost inhuman hatred for all that is not Grineer."
Lotus: "Eliminating Ruk will allow us to regain control of this system."
"What flesh is within that warframe? I will crush it. I will fill my lungs with your death."
"Forget the Lotus. Grineer are your masters. Submit for mercy."
"Too easy. I expected more. I deserve a challenge."

Sargas Ruk is first mentioned in the Gradivus Dilemma, engaging in hostile rhetoric and then open warfare against Alad V, while courting Tenno mercenary aid to reinforce his troops. He would ultimately emerge victorious, with Mars being added to the Grineer Empire. Shortly afterward, the Grustrag Three Codex entry implies that Ruk was their original commanding officer. Ruk is mentioned by the Grineer propagandist on the Radio Scanner, as well as in the Codex description of Rathuum Executioner Dok Thul. Sargas Ruk makes appearances in both Operation: The Pacifism Defect and the Pyrus Project, both times trying to destroy Grineer who have deserted his command. Most recently, he has been seen in Operation: Scarlet Spear, attacking both the Sentients and the Tenno trying to stop them. The xeric shrub Ruk's Claw, found only at Grineer Settlements on Mars, may be named after Sargas Ruk.
